TAZ batch 1 to batch 2 changes -As of 7/03/2013 Added Features LCD panel Full metal electronics enclosures Laser cut parts Improved Printed parts for reliability Shielded motor wires to improve EMI performance Parts that have changed ======================= Extruder Body v3.7.11 Remodeled in Freecad Break away supports added for bearing hole and idler tab All hole sizes slightly increased so no drilling required. Slightly taller to incease the strenght around the M4 nuts for the idler screws Cut out to make room for larger flang on ilder Location of all major parts are still the same as v3.6 extuder body Backwards compaitble with old extruder idler, washer, and latch Extuder Idler v3.1.3 Remodeled in Freecad Larger diamter flange for the M3 nut for increased strenght Rotated M3 nut for easier bridging NOT backwards compatiable with v3.6 extruder body Increased the thickness of the upper part of feed guide to increase strenght Extuder Washer v3.1 Remodeled in Freecad Backwards compaitble with old extruder body Herringbone Gear Small v1.1 Remodled to a higher resolution stl - allows for smoother and faster printing Inceased the width and length of the entraped M3 nut hole slightly so less cleaning requried Backwards compaitble with Herringbone Gear Large v1.0 Herringbone Gear Large v1.1c Remodled to a higher resolution stl Small 1.5mm chamfer on base of gear teeth to allow for easier part removal Backwards compaitble with Herringbone Gear Small v1.0 X-Carriage v1.5 Changed direction of wire exit Extended belt clamps Removed extra holes Backwards compatible X-Idler v1.2 Added extra tab to hold bearing straight Backwards compatible X-Motor v1.2 Added fillet to improve strenght to corner by switch mount Added small hole for switch wire strain relief Backwards compatible Z-Motor-Mount v1.2 Added new thermal insert hole for rod set screw Backwards compatible Y-lder v1.3.b Closed gap for Bearings to reduce stress on part Added fillets to prevent breaking on tabs Added small breakaway pads on corners to prevent warping Remodeld again in FreeCad and exported with higher resoulution (finer mesh) Backwards compatible Inner Spool Mount v1.2 Remodeled in Freecad Cut down mass of part to save plastic and time printing Made the cutout for the nut shallower Put mounting screws on the outside instead of inside Backwards compatible Strain relief bars New design to go in metal electroincs case Power Supply Cover v1.4 with Skirt 1.0 Now has a custom made "skirt" that fits around the power supply cover to prevent warping and cracking Skirt has a wide "brim" at the base so it does not peel up and warp Parts that have been replaced ============================= Plastic Enclosure All metal electronics enclosure - WIP Z-top Laser cut replacement - WIP Frame connector Laser cut replacement - WIP Name Plate Laser cut replacement -WIP Parts that have not changed but have been resliced ================================================== Bed fingers Bed corners Bearing holder Double bearing holder Feed tube holder Feed tube spinner Z-Nut Spring Outer Spool Holder Extruder Latch Extruder Mount Belt Clamp X-Carriage Guide Y-Motor Mount Y-Belt Mount v2.3 Y-Mount Chassis v1.3
